Abstract

PVA:PEG/MnCl2 composites have been prepared by adding (MnCl2) to the mixture of the poly vinyl alcohol (PVA) and poly ethylene glycol (PEG) with different weight percentages (0, 2, 4, 6, 8 and 10) wt.% by using casting method. The type of charge carriers, concentration (nH) and Hall mobility (μH) have been estimated from Hall measurements and show that the films of all concentration have a negative Hall coefficient. In D.C measurement increase temperature leads to decrease the electrical resistance. The D.C conductivity of the composites increases with the increasing of the concentration of additive particles and temperature. The activation energy decreases for all composites with increasing the concentration of the additive particles. The A.C conductivity increases with increasing of the frequency and the concentration of MnCl2 particles. The A.C electrical properties show that the dielectric constant and dielectric loss of the composites decrease with increasing of the frequency.

Highlights

Polymeric materials were given a great interest, such as the ease of fabrication, low cost, light weight, ease of chemical modification and excellent insulation or good conduction properties, in many industrial application owing to their desirable characteristics and properties which made them favorable compared to other commercial materials [1,2]
Considerable efforts focused on an applied research in the field of polymer composites to turn these materials into useful products for electronic industry
Many reports have appeared in literature dealing with the effects of the filler concentration, frequency of the applied field and temperature on the physical properties of the conductive polymer composite such as impedance, dielectric behavior and electrical conduction [3,4,5]

Summary

Introduction

Polymeric materials were given a great interest, such as the ease of fabrication, low cost, light weight, ease of chemical modification and excellent insulation or good conduction properties, in many industrial application owing to their desirable characteristics and properties which made them favorable compared to other commercial materials [1,2]. Many reports have appeared in literature dealing with the effects of the filler concentration, frequency of the applied field and temperature on the physical properties of the conductive polymer composite such as impedance, dielectric behavior and electrical conduction [3,4,5]. The electrical properties of PVA:PEG/MnCl2 composites is investigated as a function of applied frequency and concentration to use this polymeric materials in many industrial applications owing to their desirable characteristics and properties which made them favorable compared to other commercial materials.
